Abstract
A nitride semiconductor light-emitting device includes: a semiconductor light-emitting chip held on a mounting surface of a mounting substrate, having a growth surface that is a nonpolar or semipolar plane, and emitting polarized light; a reflector surrounding the semiconductor light-emitting chip when viewed in plan and having a reflective surface off which the polarized light is reflected; and a coupler held on the mounting surface of the mounting substrate and holding the reflector such that the reflector is rotatable around the semiconductor light-emitting chip.

A nitride semiconductor light-emitting device comprising:
- a mounting substrate;
- a semiconductor light-emitting chip held on a mounting surface of the mounting substrate, having a growth surface that is a nonpolar or semipolar plane, and emitting polarized light;
- a reflection member surrounding the semiconductor light-emitting chip when viewed in plan and having a reflective surface off which the polarized light is reflected;
- and
- a coupler held on the mounting surface of the mounting substrate and holding the reflection member such that the reflection member is rotatable around the semiconductor light-emitting chip, wherein out of an upper surface of the reflection member and an upper surface of the coupler, at least the upper surface of the reflection member includes a marker enabling determination of an angle of the reflective surface relative to a polarization direction of the polarized light.
